What undertaking means
An undertaking is a promise the law treats as binding in itself.
It is not a contract in the ordinary sense, and it does not need consideration. What gives it force is who it is given to and in what setting.
An undertaking to a court binds because the court accepts it and can enforce it. A party who undertakes not to deal with an asset pending trial is in the same position as if an injunction had been granted, and breaking it is contempt.
An undertaking given by a lawyer, on behalf of a client or personally, binds the lawyer. It is enforceable by the court through its supervisory jurisdiction over legal practitioners, and separately through professional disciplinary processes. That is precisely why the other side accepts it: the promise is backed by the practitioner's own position, not only by the client's good faith.
How it is used
Undertakings appear at the practical joints of a transaction or a case.
In litigation, a party may offer an undertaking instead of having an injunction made against them, which is often the sensible commercial answer.
When an interim injunction is granted, the applicant is generally required to give an undertaking as to damages: a promise to compensate the respondent if the injunction turns out to have been wrongly granted. It is the price of obtaining relief before the case is decided, and it is a real exposure.
In property transactions, undertakings between solicitors are how completion works. One firm undertakes to hold documents to the order of the other, or to register a transfer, or to discharge an existing mortgage from the proceeds. Money changes hands on the strength of them.
In corporate transactions the same mechanism is used to bridge the gap between payment and delivery of documents.
An undertaking should be given in writing, in precise terms, and only where the giver actually controls the thing they are promising.
Key features
- A formal promise binding without consideration
- An undertaking to a court is enforceable as if it were an order
- Breach of an undertaking to a court can be contempt
- A solicitor's undertaking binds the solicitor personally
- An undertaking as to damages is required to obtain an interim injunction
- Should be in writing and in precise, limited terms
How this works in Nigeria
Undertakings between legal practitioners are the mechanism that makes Nigerian conveyancing and corporate completions workable.
A buyer's lawyer pays away the purchase money against an undertaking from the seller's lawyer to deliver the executed deed and title documents. Neither side has to trust the other personally, because the undertaking is enforceable against the practitioner who gave it.
That makes precision essential. An undertaking should say exactly what will be done, by when, and on what condition. Vague undertakings, or undertakings to procure something a third party controls, are how practitioners end up personally exposed for something they cannot deliver.
The Rules of Professional Conduct for legal practitioners treat undertakings seriously, and failure to honour one is a disciplinary matter as well as a matter the court can address.
The undertaking as to damages is the other one worth understanding before applying for an injunction. A claimant who obtains an interim injunction, and then loses at trial, can be required to compensate the respondent for the loss the injunction caused. Applicants and their advisers should weigh that before rushing to court.
Undertaking vs injunction vs guarantee
Three ways behaviour is secured, with different mechanics.
An injunction is imposed by the court. A party is ordered to do or not do something, and breach is contempt.
An undertaking is volunteered and accepted. The party promises the same thing, the court records it, and it is enforced in the same way. Offering one often avoids a contested application, and avoids an order being made against you.
A guarantee is a promise about somebody else's obligation, given to a private party rather than to a court, and enforced as a contract.
The practical difference between the first two is tone rather than force. A respondent who offers an undertaking gets the same outcome as an injunction without the finding, which can matter commercially and reputationally, and courts generally accept them where they are clear.
Limits and risks
An undertaking binds only what it actually says. Vagueness cuts both ways, and a party relying on a loosely worded undertaking may find it covers less than they assumed.
A practitioner who undertakes something outside their control has taken on a personal exposure they may not be able to discharge, and that is a genuine professional risk rather than a theoretical one.
An undertaking as to damages is only as good as the applicant's means. A respondent restrained by an injunction obtained by a claimant with no assets has a promise worth very little, and courts sometimes require security.
And enforcement still takes a court application. Breach does not remedy itself, and the wronged party has to go back before a judge.
Worth knowing
Never give an undertaking to do something a third party controls. Undertake to do what is within your own power, in precise terms, with a deadline, because an undertaking is enforced against the person who gave it regardless of why they could not deliver.
Questions people ask
What is a legal undertaking?
A formal promise, usually given to a court or by a lawyer to another party, which binds without consideration. An undertaking to a court is enforceable as if it were an order, and breach can be contempt.
What is an undertaking as to damages?
A promise given by an applicant when obtaining an interim injunction, to compensate the respondent if the injunction turns out to have been wrongly granted. It is the price of obtaining relief before the case is decided.
Why do lawyers give undertakings in property transactions?
Because they let money and documents move without either side having to trust the other personally. The undertaking is enforceable against the practitioner who gave it, both by the court and through professional discipline.
What happens if an undertaking is broken?
An undertaking to a court can be enforced as contempt. A solicitor's undertaking can be enforced by the court through its supervisory jurisdiction and is also a professional disciplinary matter.
Is an undertaking better than an injunction?
For a respondent, often yes. Offering an undertaking produces the same practical outcome without an order being made against you, which can matter commercially. Courts generally accept clear undertakings.
What should an undertaking say?
Exactly what will be done, by when, and on what condition, and only in relation to things within the giver's own control. Undertaking to procure something a third party controls creates a personal exposure you may not be able to discharge.
